Photoluminescent Properties of CoMoO4 Nanorods Quickly Synthesized and Annealed in a Domestic Microwave Oven

A simple way to prepare and -CoMoO4 nanorods is reported in this paper. CoMoO4·xH2O nanorod precursors were obtained using the microwave-assisted hydrothermal (MAH) method. By annealing the as-prepared CoMoO4·xH2O precursor at 600 ̊C for 10 min in a domestic microwave oven, and -CoMoO4 nanorods were prepared. These powders were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform Raman microscopy and ultraviolet visible absorption spectroscopy (UV-vis spectra) as well as photoluminescence (PL) measurements. Based on the results, these materials revealed nanorod morphology. PL spectra obtained at room temperature for and -CoMoO4 particles exhibited maximum components around the blue light emission. The results show that the domestic microwave oven has been successfully employed to obtain and -CoMoO4 nanoparticles.
